Influence of HRT on prognostic factors for breast cancer: a systematic review after the Women's Health Initiative trial

INTRODUCTION: Mortality due to breast cancer has been reported to be the same or even lower in HRT users than in non-users. This has been attributed to earlier diagnosis and to better prognosis. Nevertheless, more advanced disease in HRT users was reported recently by the Women's Health Initiative (WHI) study. The objective of this study was to assess, using a systematic review of current literature, whether the data of the WHI study are in contradiction to observational data. METHODS: We selected 25 studies, for which we evaluated the methodology, the characteristics of the studied populations, confounding breast cancer risk factors and prognostic indicators. RESULTS: The WHI study, showing a worsening of some prognostic parameters, is in contradiction to most published observational studies. Most observational studies are retrospective, not well matched and did not consider most confounding factors. Their methodology and selection criteria varied considerably and the number of patients was often small. No differences in the distributions of histology, grade or steroid receptors were observed in the WHI trial, while this was the case in some of the observational studies. Other parameters (S phase, protein Neu, Bcl-2 gene, protein p53 and E-cadherin, cathepsin D) were not reported in the WHI trial. CONCLUSIONS: In view of these data, the current clinical message to patients should be changed: one can no longer declare that breast cancers developed while using HRT are of better prognosis.     

褐云玛瑙螺中枢内支配大触角肌肉神经元的分布

实验用荧光素Ｂｂ逆行追踪方法，研究了褐云玛瑙螺支配大触角肌肉活动的神经元在中枢的分布，结果表明，Ｂｂ标记神经元大多分布于同侧脑节，少量分布于侧脑节，同侧口球节，足节和侧节，Ｂｂ标记神经元大多为中小型神经元，个别属于大型神经元。     

大肠癌及癌前病变的粘液组化研究

应用粘液组化方法AB—PAS、HID—AB、OR—AB、PAT—KOH—PAS、PATB—KOH—PAS显示大肠上皮分泌粘液的类型。结果发现:大肠慢性炎、大肠克隆病及炎性息肉、增生性息肉、幼年性息肉分泌粘液类型与正常粘膜相似(P>0.05),而伴有异型增生的溃疡性结肠炎、管状腺瘤、绒毛状腺瘤、家族性息肉、腺瘤癌变、大肠癌及癌旁粘膜粘液分泌性质与量均有变化。在这些病变中氮乙酰化及含有邻位羟基的氧乙酰化粘液阳性率明显高于正常粘膜(P<0.05)。其检出阳性率与异型增生的程度有关。笔者认为应用粘液组化方法分析大肠癌前病变粘液性质对于判断粘膜上皮恶性倾向提供了有价值的手段。

Biochemical Changes after Vertical Banded Gastroplasty for Morbid Obesity

A prospective study of biochemical changes after vertical banded gastroplasty for morbid obesity, in 94 patients (10 males and 84 females, ages ranging from 18 to 59 years) has been carried out. Liver function tests and electrolyte estimations were performed preoperatively, during hospitalisation for surgery, at 6 weeks and at 6 months postoperatively, and demonstrated no significant changes in liver function in these patients 6 months after surgery. The study concludes that there is no increase in the risk of liver damage or electrolyte disturbance after vertical gastroplasty, but that there may be subtle hepatic changes present as gall bladder disease developed in 18 patients postoperation (19%).
